Example text

G. color = ∗ denotes any color). Let complex c denote a set of selectors and let length n of the complex denote the number of selectors (simple or advanced) contained in the complex. For example complex c = s1 , s2 , s3 , has length 3 (where s j , j = {1, 2, 3}, is a selector). A complex is understood as a conjunction of selectors. Coverage of selector s, cov(s) is the number |D s | of events that satisfy condition in s divided by |D|. Coverage of c, cov(c) is the number |D c | of events that satisfy complex c divided by |D|.

Creation of the ruleset has to be finished because each single selector in complex must describe a different attribute (complex cannot be any longer). According to the second criterion, the algorithm is stopped when the set of new candidates is empty (if there are no parents that have common part of n − 1 length and new candidates cannot be created). 3 Third Step—Merging of Complexes In this step, the number of created and evaluated complexes is decreased and their quality improved. If some complexes are based on the same attribute set and only one selector has different value, then it is possible to merge such complexes.
